Há 3 dias · It was solved with the BCS theory of superconductivity, proposed by John Bardeen, Leon Neil Cooper, and John Robert Schrieffer in 1957. Feynman at the Robert Treat Paine Estate in Waltham, Massachusetts, in 1984
Há 5 dias · The invention of transistors, by Bardeen and Brattain in 1947, awarded with a Nobel prize, is regarded as one of the most important discoveries of the 20th century. Transistors are the basis...
Há 3 dias · The invention of the transistor in 1947 by John Bardeen and Walter Brattain marked a pivotal moment in semiconductor history. While the operational mechanics were initially unclear, John Shive's experiment in 1948 confirmed that the transistor's operation was based on bulk conduction, aligning with William Shockley's theory on p-n ...
Há 5 dias · 1. What were John Bardeen’s major contributions to science? John Bardeen is best known for his co-invention of the transistor, which revolutionized the field of electronics. He also made significant contributions to the development of superconductivity and received multiple Nobel Prizes for his groundbreaking work in these areas. 2.
Há 18 horas · John Michell used the term "dark star" in a November 1783 letter to Henry Cavendish, and in the early 20th century, physicists used the term "gravitationally collapsed object". Science writer Marcia Bartusiak traces the term "black hole" to physicist Robert H. Dicke , who in the early 1960s reportedly compared the phenomenon to the Black Hole of Calcutta , notorious as a prison where people ...
Há 4 dias · In 1947, the invention of the transistor by John Bardeen, Walter Brattain, and William Shockley at Bell Laboratories marked a significant milestone in electronics. This small yet powerful semiconductor device revolutionized the field, leading to the development of smaller, more efficient electronic devices and the eventual emergence ...
Há 5 dias · Teoría BCS. La explicación más aceptada de la superconductividad viene de la Teoría BCS. Desarrollada por John Bardeen, Leon Cooper y Robert Schrieffer en 1957, esta teoría plantea que, a temperaturas suficientemente bajas, los electrones en un material superconductor forman parejas de Cooper.
